8 Claims.

My invention relates to textile frames or machines of the spinning or twisting type including those for cap spinning, fly spinning, and other methods of spinning wherein textile spindles are employed, and is particularly directed to the means for lubricating the spindle and the parts carried thereby and located adjacent thereto.

I-Ieretofore in lubricating devices of this type the openings in the reservoir or casing for the reception of the lubricant have become clogged and ultimately closed, and the contents contaminated, by accumulations of lint, dust, and other foreign matter.

It is an object of the present invention to prevent the above deleterious results.

Further objects of the invention are to facilitate the introduction of the lubricant into the reservoir; to thoroughly and automatically seal the openings; to facilitate the feeding of the lubricant to the absorbent element; to afford means for priming the device; and to enable the replenishment of the reservoir without danger of accidentally forcing any of the contents of the reservoir through the receiving openings.

Additional objects are to attain the above results in a simple and inexpensive structure, capable of "formation from struck up thin metal, and with little labor, and adapted to accommodate itself to spindles of different diameters.

Other objects and advantages of the invention will hereinafter be adverted to or be apparent from the following description taken in connection with the accompanying drawings.

To the ends herein-above adverted primarily my invention consists in such parts and in such combinations of parts as fall within the scope of the appended claims.

Two forms which the invention may assume is illustrated in the accompanying drawings, but such showing is for illustrative purposes solely, and are not purposed to define the limits of the invention.

In the accompanying drawings,

Figure 1 is a side elevation, partly in section illustrating my lubricating device applied to a machine of the cap spinning type,

Figure 2, a perspective view of the lubricating device,

Figure 3, a fragmentary central section of my device and of portions of the machine adjacent thereto, the parts of the former being shown in normal closed position,

Figure 4, a similar section of the same showing the parts in filling position,

Figure 5, a section taken on line 5-5 of Figure 3, and

Figure 6, a section corresponding to that of Figure of a modified form of my invention.

In the drawings in indicates the bolster rail, ii the spindle fixed therein, I2 the lift rail through which the spindle loosely passes, M the whirl, it the package carrying tube fixed to the latter and rotated thereby, and It the cap, of a cap-spinning mechanism all of familiar construction and operative in the usual manner.

ll represents in a general way my lubricating device loose on the spindle and resting on the lift rail, and I3 a fiber washer loose on the spindle,

resting on the member IT, and supporting the whirl.

My lubricating device includes a reservoir 20, having an upper section or cover and a lower section or well 23 and 22 respectively. The former comprises an annular top 23 with a depending peripheral flange 24, and the latter section, an annular bottom 2'5 with an upwardly directed peripheral flange 26 overlapped and frictionally engaged by the flange 2d. The flanges form a cylindrical side wall. The inner peripheral margin of the top 23 is formed with a hollow annular shoulder 23 A sleeve 27 in the central openings of the plates loosely surrounds the spindle I l and is fixed as at 23 by solder or otherwise to the plate and has upon its upper end an annular bgaring flange it overlapping and engaging the shoulder of the top 23. The bottom 25 is provided adjacent the sleeve N with an annular internal shoulder 3d. The top 23 is provided with diametrically oppositely disposed lubricant receiving openings 3i, and the bottom 25, with a lubricant feed or discharge opening 32 leading from the lubricant storage chamber 33. An opening or hole 3 5 in the sleeve is for venting purposes. This opening is above the level of the lubricant within the horizontal plane of shoulder portion of the top 23.

Upon the bottom of the reservoir rests the lower end of a helical spring 3T whose upper end presses against an annular closure or sealing plate 3% vertically slidable, with suitable clearance, in the lower section of the reservoir, and comprising a fiat body portion 39 normally tightly abutting against the top of the casing and closing and sealing the receiving openings 3|, and an annular downwardly inclined portion 48 provided with an annular series of recesses 4| forming interspaced downwardly inclined peripheral projections 42.

A downwardly extending shell or disk holder 44 comprises a cylindrical wall 45 frictionally em bracing the side of the reservoir, an annular horizontal base 41, and a centrally disposed upturned annular flange 48 having its end abutting against the bottom of the reservoir and forming a cylindrical recess or socket 49 in which is frictionally seated an annular disk 50 of felt or other absorbent material snugly surrounding, but slidable upon, the spindle H, and contacting with the bottom of the reservoir as well as covering the feed opening 32 through which the disk receives its supply of lubricant from the reservoir.

In the vertical plane of the lubricant receiving openings 2| the wall 45 of the shell is provided with a slot 52 to allow the passage of the attaching lip 53 of a. depending lug 54. The lip is fixed to the section 22 by solder or otherwise. The lug is adapted to engage the edge of the lift rail to prevent circular movement of the lubricating device [1.

In the modified form of my device shown in Figure 6 the shell or disk holder 4 8 is omitted, and the annular lubricating disk 56 is located in an annular recess 57 in a lift rail 58 flush with the top of the latter adjacent or in contact with the bottom of the reservoir 20.

In order to replenish the reservoir the nozzle 9 of a lubricant container is manually pressed downwardly upon the sealing plate through one of the openings 3|, as shown in Figure 4, thereby tilting the plate to its lowest limit with one or more of the teeth 42 adjacent or contacting with the shoulder 30, until the receptacle is filled. During the filling interval the lubricant is permitted free passage below the plate 38 through the relief recesses 4| of the latter whereby the liquid may be so evenly distributed in the receptacle that the return of the plate to horizontal will not cause escape of any lubricant through the opening M from which the spout is withdrawn.

By reason of the cooperation of the spring 32 with the closure plate 38 the latter automatically returns to closing position when the spout is remove-d, and is maintained so tightly against the top of the reservoir that the openings iii are sealed against the penetration of lint, yarn, fiber and other particles that accumulate around a spindle lubricant device.

In operation the lubricant is fed by gravity through the opening 32 which saturates the absorbent member 59 or 56 which in turn smeaFs the lubricant upon the spindle as the lift rail l2 or 58 travels up and down in its traverse movement. The flow of the lubricant through the opening 32 is facilitated by the presence of the vent opening 34.

The described reciprocation of the absorbent member adequately lubricates the package carrying tube l sumciently to prevent overheating of the latter.

The fiber washer i8 lessens the wear and the vibration which at high speeds occasionally occurs when the whirl I4 is in direct contact with the reservoir portion of my device.

The portion 29 of the spindle bearing sleeve 27 assists in locating the latter during the original assembling of the parts of the reservoir, it being understood that the thickness of the sleeve must vary according to the diameters of different spindles.

It will be observed that all 'of the parts of the device 4's are composed of parts out and struck up from thin metallic blanks, and is therefore inexpensive to form and assemble.

Those skilled in the art will readily realize that the particular mechanism herein shown may be variously changed and modified without departing from the spirit of my invention or sacrificing the advantages thereof, and that the disclosures herein are illustrative only, and my invention is not limited thereto.
